Beryl Var Goshenite -Highly etched crystal.
stock #16.1-332
Urucum Mine, Galileia
Minas Gerais, Brazil
3.8 x 2.6 x 1.8 CM (small miniature/ large thumbnail (toenail))
price: $440
Spring 2020

Perfect, gemmy and absolutely colorless, this looks just like ice. A natural sculpture of a single etched Beryl crystal, this is also a complete floater. Every surface is complexly faceted, etched and undamaged. Not many minerals can exhibit this degree of sharp sculptural etching, however we see this with Beryl from a few finds and these can be incredible in person. True colorless Beryl (Goshenite) is also quite uncommon. This specimen is displayable from any side or angle, the larger faces are smoothly curved yet striated and it is fully transparent with no inclusions, veils or cracks. Choice gem..

Beryl var. Goshenite - highly etched crystal
stock #16.1-333
Urucum Mine, Galileia
Minas Gerais, Brazil
5.6 x 3.5 x 1.8 CM (small cabinet/ large miniature)
price: $340
Spring 2020

Perfect, gem clear and absolutely colorless, this looks just like ice. A natural sculpture of an etched Beryl crystal, this is also a complete floater, every surface is complexly faceted, etched and undamaged. Not many minerals can exhibit this degree of sculptural etching, however we do see this with Beryl from a few finds and these can be incredible in person. True colorless Beryl (Goshenite) is also quite uncommon, this specimen is displayable from any side or angle, the larger faces are smoothly curved yet striated and it is fully transparent with no inclusions, veils or cracks. Choice.

Datolite (color change) and Heulandite
stock #8.1-208
Prospect Park Quarry, Prospect Park, Passaic County
New Jersey, United States
5.1 x 3.2 x 2.8 CM (small cabinet/ large miniature)
price: $250
Spring 2020

Datolite with a strong color change from artificial to daylight, the color goes from a dark olive-green to a yellow-grey. From a remarkable pocket at the classic Prospect Park Quarry locality in 2008, there were not many pieces found. This has contrasting Huelandites with a warm brown color and shows the uncommon color change phenomenon very well. The Datolite is transparent with many faces being very glassy. There is contacting and bruising that can be hidden fairly well by display angle, so not for perfectionists. Overall the condition is equal to the best I have seen from this find, and a cute Northeastern USA oddity.

Corundum (var. Ruby) single crystal
stock #AC-099
Mundarara Mine
Arusha Region, Tanzania
6.6 x 3.6 x 2.8 CM (cabinet)
price: $150
Spring 2020

A single doubly terminated Corundum crystal that shows classic form and habit. This is vividly fluorescent an intense red which is normal for Ruby. The terminations are flat, smooth and have some intersecting lines visible. The crystal faces have typical very rough texture. Strong light penetrates the sides of the crystal showing some degree of translucence. Older specimen (1960's vintage) with nice form and great fluorescence.

Rhodochrosite with Quartz
stock #10.1-194
Wutong Mine, Liubao, Cangwu Co. Wuzoh Pref.
Guangxi Province, China
2 x 1.6 x .8 CM (thumbnail)
price: $155
Spring 2020

Small, but very cute, cluster of sharp and slightly-etched Rhodochrosite rhombs. Several faces show complex stepped modifications that add extra pop. Aside from a tiny spray of Quartz crystals, there is no matrix, just Rhodochrosite. This thumbnail from an important find at Wuzoh in 2009, this was one of the last of this form, as most later pockets have more flattened and disk-like crystals. Nice color, form and presentation, if this was larger, it would be a very costly specimen!

SOLD Franklinite, single complete octahedron
stock #SOLD 15.1-628
Franklin Mine, Franklin Mining District, Sussex County
New Jersey, United States
2.9 x 2.7 x 2.1 CM (thumbnail)
price: $0
Spring 2020

A single black octrahedral crystal from vintage 1930's ex. Warren Johansson collection. Dr Johansson was a prolific field collector and active trader well into his nineties. His label is with the specimen. Very nice face modifications and a slight melted look as is classic for the specie. Most Frankinites have considerable damage or are incomplete, but this one is all there, with only minor edge rough spots and one clean contact. Of course this is from the type locality which is really the only source of any sizable crystals worldwide, yet these were at one time plentiful in Franklin. A nice piece that can fit a Thumbnail box but just barely.

Crocoite on Gibbsite
stock #20.1-214
Adelaide Mine Dundas Mineral Field, Zeehan District,West Coast Municipal
Tasmania, Australia
9.5 x 6 x 2.6 CM (cabinet)
price: $390
Spring 2020

Slender bright red-orange crystals of Crocoite rise above a contrasting white Gibbsite matrix. A choice specimen with most crystals in good shape, terminated and a few with hoppered form. Minimal damage as is almost inevitable with this sort of fine needles, but most is not visible by naked eye. From a 2014 pocket, this has the color and luster that is most desired, the needles are up to 1.6 CM.

Babingtonite with Prehnite and Quartz
stock #20.1-213
Hongquizhen Quarry, Meigu County, Liangshan Yi Pref.
Sichuan Province, China
7.8 x 6.1 x 3.9 CM (cabinet)
price: $450
Spring 2020

a cluster of sharp Babingtonite crystals perched nicely on a matrix of Prehnite and clear Quartz crystals. The Babingtonite has good mid range natural luster, in our experience the very bright luster on some pieces is often a result of an oiling or plastic coating, which is for us a form of fakery. This is clearly a fully natural specimen ex Shields Flynn collection. For almost a century the wolds best Babingtonites were from a small quarry in Western Massachusetts. Very few were ever found of this size and quality. Even today a specimen from Massachusets this fine would be sold quickly for thousands. The Chinese discovery has allowed many more people to own a choice piece for reasonable cost..
